People are definitely becoming more and more concerned about the environment, also more inventive. Looking for ways to save up energy, the staff of the Helsinki Sea Life Center aquarium in Finland, discovered they had a totally free energy source living right in their fish tanks – electric eels.
“Our electrician built a device that uses four plastic-encased steel probes to capture the eel’s electrical discharge and feed it to the lights. At feeding time though, it really powers up. You can hear the voltage increasing and the lights shine bright and steady.” explains Markus Dernjatin – from the Helsinki Sea Life Center in Finland.
These deadly deep sea creatures can produce an amount of electrical energy sufficient to light up more than one Christmas tree – around 650 volts. At the same time, the high voltage is enough to kill a grown man…
As a way of battling the summer heatwave that hit Japan this year, authorities have inaugurated a frozen aquarium that will keep visitors cool and entertained.
Kori no Suizokukan is located in Kesennuma, Miyagi Prefecture and features around 450 specimens of around 80 species of marine wildlife, all captured at a nearby sea port. Visitors can enjoy a brief break from the scorching sun and admire all sorts of fish, crabs or octopuses, as well as unusual objects like action figures, bottles of sake, or flowers, all embedded in huge blocks of ice.
The Frozen Aquarium was inaugurated, in Kesennuma’s fish market, in 2002, and uses flash-freezing technology to conserve fresh specimens and keep them looking so good.
While the Frozen Aquarium is a welcome tourist attraction, visitors can only spend a few minutes inside. Because temperatures inside the aquarium reach -20 degrees Celsius, a special suit is needed to keep people from becoming freezing exhibits themselves. Without these special suits, visitors would start feeling severe pains in just five minutes time.
